Abstract :
In this paper, we demonstrate statistical identifications for the time series of velocity of the movements of limbs in young infants during the conjugate reinforcement mobile task. The mean square velocity and the probability density function (PDF) of the time rate change of velocity are estimated. We found that the PDF is universally symmetric with a sharpened peak at the origin and exponential-tails. The result suggests that the PDF is a useful measure that reflects the motor pattern generation and memory formation during the mobile task
